SPECIFICATION forming part of Letters Patent No.731,361, dated June 16, 1903. Application filed May 20, 1902. Serial No. 108,168. (No model?)

HAWKINS, vided with pinions 14 14, engaging toothed of Boston, inthe county of Suffolk and State segments 15 15 on the ends of a pivoted'horiof Massachusetts, have invented certain new zontally-swinging arm or lever 16. By virtue 5 and useful Improvements in Car-Seats, of of this connection between the chairs they 55 which the following is a specification. are caused to rotate in unison, so that both This invention relates to seats for use in chairs may be rotated by grasping either one railway-cars of the type employing a swingof them and reversing it. ing support anda lpair of chairs mounted to 17 isa spring-pressed locking-bolt adapted f' zo rotate on said support, so as to face toward to engage a series of notches 1S, formed in 6o either end of the car, the support being adaptthe lever 16, whereby the said lever is looked ed to project either crosswise of the car or so as to hold the chairs in different rotative lengthwise thereof, the seats then facing the positions on `the support 11, but permiting aisle of the car. Seats of this nature have said chairs tol be automatically unlocked by `l5 heretofore employed means for locking the the exertion of sufcient rotative force. 65 chairs in xed angular positions on the swing- I do not herein claim the specific form of ing support and independent means for lookconnection and locking means above deing the swinging support in fixed angular poscribed, as the saine is made the subject of a sitions on its base. separate application, Serial No. 91,9721, tiled zo The object of the present invention is to by me. y 7o provide means whereby the swinging sup- For the purpose of locking the swinging port may be automatically unlocked from its arm 11 in diderent rotative positions on the base by the rotation of the chairs on said base 1O I provideavertically-slidinglockingsupport.

In other words, the righthand chair has a movement ot' rotation, but no movement of translation. The base l0 can therefore be located with the vertical axis of the chair at a distance from the side ofthe car corresponding to the horizont-al distance from said axis to the most protrusive part of the chair-back, thereby securing a maximum amount of aisle-space when the chair-arm 11 is thrown longitudinally of the car.

I do not wholly confine myself to the constructional' embodiment of my invention herein set forth, as theautomatie unlocking of the swinging support can be obtained by many methods ditferin'g'in detail.

I claiml. In a car-seat, the combination of aswinging support', means to lock said support against swinging movement, a chair mounted to rotate on said support, and mechanism actuated bythe rotation of said chair for automatically releasing said locking means.

2.- In acar-Seat, the combination of a swinging support, means to lock said support against swinging movement, two chairs mounted to rotate on said support, and mechanism etuated by the rotation of either of said chairs for automatically releasing said locking means.

3. In a car-seat, the combination of a swinging support, means to lock said support against swinging movement, two .chairs mounted to rotate on said support, a connection between said chairs for causing them to rotate in unison, and means on said-connection for automatically releasing said locking means when the chairs are rotated.

4. In a car-seat, the combination of a base provided with a locking member, a support mounted to swing on said base, a locking-bolt carried by said support and adapted to engage said locking member, means yieldingly pressing said bolt into engagement with said locking member, a chair mounted to rotate ou said support, and a camoperated by the rotation of said chair and adapted to force said bolt out of locking engagement with said locking member.

In testimony whereof I have affixed my signature in presence of two witnesses.
